Specification of Letters Patent.

Patented July 29, .1 91 3.

To aZZ whom 2'15 may concern:

Be it known that I, EDGAR GILES, a citizen of the United States,residing at White Lake, in the county of Aurora and State of SouthDakota, have invented new and useful Improvements in lVindowShelfBrackets, of which the followingis a specification.

This invention relates to brackets; and it has for its object theprovision ofa deviceof this character which may be readily connectedwith the side bars of a window casing and arranged therein so as toeffectually support a platform on which may be accommodated flowerreceptacles orthe like.'

Another object of the invention is the provision of a bracketwhich willbe adjustable whereby to accommodate itself to window frames ofdifferent sizes.

\Vith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be hereinafter de-. scribed and claimed.

In the accompanying drawings :-Figure 1 is a perspective view of aportion of a window. showing the application of companion bracketsthereto; and Fig. 2 is a horizontal section through one of the clampingelements.

With reference to Fig. 1 of the drawings alined b tlCkGlS 1 are shownconnected with the vertical side bars A of the window casing or frame.These brackets are identically constructed and it is believed that adescriptibn of one will sutlice for the other. Each bracket includes avertical arm 2 which may be constructed from a single piece of sheetiron or suitable material and provided with an upper supporting flange 3to which is riveted or otherwise suitably secured one end of a platformsupporting arm 4, the latter being horizontally disposed the upper endof a brace 6. Said brace is extended in the direction of the lowervertical arm 2 and is terminally connected therewith through the mediumof a bolt 7. The platform supporting arm 4. is provided with verticalguardsS, which are adapted to engage against the board or platformforming member 9, as shown in Fig. 1, so as to prevent the lateralshifting of the platform when the device is in use.

The vertical arm 2 is provided with identical upper and lower clamps,the latter including plates 10 and 11, which are provided with'alinedelongated slots 12 which receive the bolt 7 From this construction, itis evident that the plates may be adjusted on each other so that theireffective clamping end can be brought into secure contact with theopposite faces of the vertical side bar of the window frame. Theeffective clamping end of the plate 11 is formed by bending one end ofthe plate at right angles to the main body portion of the plate so as toprovide a clamping jaw 13, which is provided along its vertical edgewith a series of inwardly extending teeth 14.

The clamping element of the plate 10 coir prises a jaw 15 having atoothed edge 16. Said jaw 15 is provided with hinged knuckles 17, whichare associated with similar hinged knuckles 18 of the plate 10 andconnected therewith through the medium of a pintle 19.. Through thisconnection, it evident that the jaw 15 may be adjusted angularly withrelation to the jaw 13,,

The jaw 13 is provided with a threaded opening 20 which receives acorrespomlingly threaded end 21 of a clamping bolt 22. The opposite endthe bolt is extended through a slot 23 in the movable jaw 15 andprovided with a manipulating crank portion 94, which may be operatedmanually so as to adjust the bolt in a horizontal direction and therebyeffect relative angular adjustments of the companion jaws 13 and 15. Thesaid bolt is preferably upset, as at 25 and provided with a nose 26which is adapted to engage against the jaw 15 and thereby move the sameon its .pintle when feeding the bolt in one direction.

The upper clamp includes clamping ole ments l0 and 11 which areidentical with the lower plates, beingconnectcd for horizontaladjustment on the vertical arm 2 through the medium of a bolt 27.

When the brackets are secured in proper alinement upon the companionside bars of the window frame, as shown in Fig. 1, a platform such as aboard or the like may be extended across the horizontal arms at andsustained in a horizontal position thereby, so as to permit flowerported thereon.

From the foregoing description. taken in connection with theaccompanying drawings,

pots or the like to be supthe construction and operation of theinvention will be readily understood without requiringa more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention, as claimed.

Having thus described my invention, what Iclaim is j 1. A bracketcomprising a horizontal arm,

a clamp carriedby said arm and comprising -hor1zontally ad ustableplates, one of sald plates terminating 1n a hxed aw having ahorizontally threaded passage therein, a pivoted jaw carried by theother plate, means for holding both plates in adjusted positions, and amember lying behind the plates and having a threaded portion adjustablein the opening of the fixed jaw and having its opposite end providedwith an integral manipulating portion having a nose extending inthedirection of the pivoted jaw and operating across the jaw and againstthe same for moving the pivoted jaw angularly with relation to the fixedjaw when said member is rotated in onedirection.

2. A bracket comprising a horizontal arm, a vertical arm, a braceconnecting the vertical arm with the horizontal arm, identical clampscarried by the bracket and'disposed at the opposite ends of the verticalarm and each embodying horizontally adjustable plates, means for holdingthe plates in ad? justed positions, one of the platesterminat ing in atired angularly bent jaw, a'horizon- In testimony whereof I afiix mysignature in presence of two witnesses.

EDGAR GILES.
